13 Early Signs of Multiple Sclerosis

MS & Vision Problems

The most common early signs of MS are vision problems, clinically called “optic neuritis.” Inflammation affects the optic nerve and disrupts central vision. This can lead to blurred vision in one or both eyes, double vision, or loss of contrast or vivid colors.
You may not notice the vision problems immediately, as degeneration of clear vision can be slow. Pain when you look up or to one side also can accompany vision loss.

Tingling & Numbness

MS affects nerves in the brain and spinal column (the body’s message center). This means it can send conflicting signals around the body. Sometimes, no signals are sent. This results in the most common symptom: numbness.
Tingling sensations and numbness are the most common warning signs of MS. Common sites of numbness include the face, arms, legs, and fingers.

Pain & Spasms

Chronic pain and involuntary muscle spasms are also common with MS. One study, according to the National MS Society, showed that half of people with MS had either “clinically significant pain” or chronic pain.

Muscle stiffness or spasms (spasticity) are also common. They involve feelings of stiff muscles or joints as well as uncontrollable, painful jerking movements of extremities. The legs are most often affected, but back pain is also common.

Fatigue & Weakness

Unexplained fatigue and weakness affect about 80 percent of people in the early stages of MS.
Chronic fatigue occurs when nerves deteriorate in the spinal column. Usually, the fatigue appears suddenly and lasts for weeks before improving. The weakness is most noticeable in the legs at first.

Balance Problems & Dizziness

Dizziness and problems with coordination and balance can decrease the mobility of someone with MS. Your doctor may refer to these as problems with your gait. People with MS often feel lightheaded, dizzy, or feel as if their surroundings are spinning (vertigo). This symptom often occurs when a person stands up.

Bladder, Bowel & Sexual Dysfunction

dysfunctional bladder is another symptom occurring in up to 80 percent of people with MS. This can include urinating frequently, strong urges to urinate, or inability to hold in urine.
Urinary-related symptoms are often manageable. Less often, people with MS experience constipation, diarrhea, or loss of bowel control.
Sexual arousal can also be a problem for people with MS because it begins in the central nervous system — where MS attacks.

Cognitive Problems

About half of people with MS will develop some kind of issue with their cognitive function. This can include:

  • memory problems
  • shortened attention span
  • language problems
  • difficulty staying organized

Depression and other emotional health problems are also common.

Emotional Health

Major depression is common among people with MS. The stresses of MS can also cause irritability, mood swings, and a condition called pseudobulbar affect:  bouts of uncontrollable crying and laughing.
Coping with MS symptoms, along with relationship or family issues, can make depression and other emotional disorders even more challenging.

Other Symptoms

Not everyone with MS will have the same symptoms. Different symptoms can manifest themselves during “attacks.” Along with the symptoms mentioned on the previous slides, MS can also cause:

  • hearing loss
  • seizures
  • uncontrollable shaking
  • breathing problems
  • slurred speech
  • trouble swallowing

Progression & Severity

MS often astounds doctors because of how much it can vary in both its severity and the ways that it affects people. Attacks can last a few weeks and then disappear. However, relapses can get progressively worse, more unpredictable, and come with different symptoms.
However, early detection may help prevent MS from progressing quickly.

Is MS Hereditary?

MS isn’t necessarily hereditary. However, you have a higher chance of developing the disease if you have a close relative with MS, according to the National MS Society.
The general population only has a tenth of a percent chance of developing MS. But the National MS Society reports that number jumps to 2.5 to 5 percent if you have a sibling or parent with MS.
Heredity isn’t the only factor in determining MS. An identical twin only has a 25 percent chance of developing MS if their twin has the disease. While genetics is certainly a risk factor, it’s not the only one.
